If you are in the market for a PA system, you have many options today, and one of the biggest choices concerns a wired or wireless PA system. Let’s take a look at PA systems and the pros and cons of both wireless and wired technology. This can help you determine which one will best serve your needs.
What is a PA System?
A PA or public address system is designed to broadcast sound over a specified distance. You need a microphone to transmit sound and an amplifier, along with speakers. The first PA systems were wired but when wireless technology became available, it did not take long for it to reach sound systems. In essence, a wireless PA system is a small version of a radio station, because you are broadcasting an audio signal over a distance, through the air.
Wired Systems
A wired PA system uses wires to amplify sound signals. This was the most common system until a few years ago, and they see less use as the years go by. However, there are still some significant benefits to consider.
Wired PA System Pros
A PA system with wires gives you an interrupted signal, and the reason is simple. There is no way for standard radio, CB, and other signals to interfere. These systems work well in large buildings and structures.
Wired PA Cons
With wires, you are limited in your space. In addition, your wires can easily become tangled, and this can be very frustrating.
When you use wires, there is always a chance someone may trip and fall. This could lead to injury and possibly lawsuits. Plus, there is a risk of damage to your equipment when you have wires.
Wires will eventually break down and fail. When this happens wires be replaced, and this will add to the overall cost.
Wireless PA System
Wireless PA systems do not depend on wires. The sound signals are broadcast over a specific frequency. A typical wireless system contains wireless microphone and speakers also.
Wireless Pros
Wireless systems are the most convenient types. You do not have to be concerned with wires getting in the way. Plus, there is less maintenance because there are no wires to fail. In addition, you won’t have to deal with tripping hazards or tangled up wires.
Wireless PA System Cons
There are very few downsides to wireless PA systems. You might get occasional signal interference, but the better units broadcast over UHF frequency to eliminate distortion and most problems. Not long ago, wireless systems were more expensive than wired ones, but the prices have come down considerably, and you can find many affordable units today.
